Description

[Detailed description of the invention] (Technical field) This invention relates to the structure of columns used in buildings that use a mixture of lightweight steel and wood materials in order to create the feel of Japanese-style architecture while using lightweight steel frames. .

(Background Art) Conventionally, as shown in FIG. 1, a bolt 3' is inserted into a nut hole 2' of an end fitting 1' bent into a U-shape. was fixed to the end of a wooden pillar 8 by nailing it with nails 9' or the like. Therefore, the protruding bolt head 5' is only in contact with the end face of the column 8 in a small area, and the load is transferred to the bolt head 5'.
Since the bolt head 5' is supported only by the pillar 8, there is a risk that the bolt head 5' may sink into the end face of the pillar 8, causing a deviation in the height of the pillar or the frame.

(Purpose of the invention) The present invention was made in view of the drawbacks of the conventional examples mentioned above, and its purpose is to prevent the head of the bolt from digging into the end face of the column, and to adjust the height of the column etc. The purpose is to keep you from going crazy.

(Disclosure of the invention) The structure of the column of the invention is such that the bolt 3 is inserted through the end fitting 1, the bolt shaft 4 is protruded to the outer surface side of the end fitting 1, and the spacer 6 is thicker than the thickness of the bolt head 5. The bolt head 5 is arranged in the inner surface of the end fitting 1 and placed in the through hole 7 bored in the spacer 6, and the spacer 6 is brought into contact with the end surface of the wooden column 8, so that the end fitting 1 is placed on the end of the column 8. The above objective can be achieved by this method.

Hereinafter, the present invention will be explained in detail with reference to the accompanying drawings. 10 is a wooden base placed on the top surface of the foundation 11 and fixed with anchor bolts or the like, and 12 is a wooden pillar erected on the base 10. Between the through-posts 12, there is a through-post hardware 1 fixed to the through-posts 12.
A beam 14 of an H-shaped lightweight steel frame is horizontally suspended via the beam 3. Reference numeral 8 denotes a wooden column (pipe column), and an end fitting 15 for the head side and an end fitting 1 for the leg side are fixed to the upper and lower ends of the column 8, respectively. The end fitting 15 for the head side and the end fitting 1 for the leg side share a U-shaped fitting 16 bent into a substantially U-shape, and the central piece 17 of the U-shaped fitting 16 has two pieces. Nut holes 2 are drilled at approximately diagonal positions, and large holes 20 for passing bolts 19 and small holes 2 for passing nails 9 are formed in both sides 18 of the U-shaped metal fitting 16.
1 is perforated. Furthermore, in the case of the end fitting 1 for the leg side, the bolt 3 is inserted into the nut hole 2, the bolt shaft 4 is made to protrude to the outside surface of the end fitting 1, and the bolt 3 is inserted into the end fitting 1. It is fixed by welding. 6 is a spacer made of incompressible material such as plywood or metal plate, and U
A through hole 7 in which a bolt head 5 is housed is bored in correspondence with the nut hole 2 of the molded metal part 16, and the thickness of the spacer 6 is larger than that of the bolt head 5, and the spacer 6 is attached to the end of the leg side. When fitted into the inner surface of the metal fitting 1, the bolt head 5 is hidden within the through hole 7. Then, the lower end of the column 8 is inserted into the end fitting 1, the lower end surface of the column 8 is brought into contact with the spacer 6, and the end fitting is tightened with the bolt 19 and nail 9 driven from the side piece 18 to the side surface of the column 8. 1 is fixed to the lower end of the pillar 8. Further, a nut 22 is welded to the inner surface of the end fitting 15 for the head side along with the nut hole 2 to increase the screwing force with the bolt. Further, the thickness of the spacer 6 is larger than the thickness of the nut 22, so that when the spacer 6 is fitted into the end fitting 15, the nut 22 is hidden within the through hole 7.
Then, insert the upper end of the pillar 8 into the end fitting 15 for the head side, bring the upper end surface of the pillar 8 into contact with the spacer 6, and drive the bolt 19 or nail 9 into the side surface of the pillar 8 from the side piece 18 to end the pillar 8. A metal fitting 15 is fixed to the pillar 8. Therefore, the column 8 has a nut portion on its upper end surface and a bolt portion on its lower end surface, and can be connected by a bolt and a nut. Therefore, when this column 8 is to be erected, for example, between a foundation 10 and a beam 14, the bolt shaft 4 on the lower end surface of the column 8 is inserted into a hole (not shown) drilled in the upper surface of the foundation 10. In order to ensure strength against pulling out, the column 8 and the base 10 are connected by a sheet metal member 23, and the upper end surface of the column 8 is connected to the beam 14.
The bolt 25 is brought into contact with the lower surface of the flange 24 of the flange 24, and is fixed by driving a bolt 25 through a hole (not shown) of the flange 24 into the nut hole 2 of the end fitting 15 for the head side.
In addition, when the column 8 is erected between the upper and lower beams 14, 14, the bolt shaft 4 on the lower end surface of the column 8 is inserted into the hole of the flange 24 of the lower beam 14 and fixed with the nut 26, and the upper Column 8 in contact with flange 24 of beam 14
Drive the bolt 25 into the nut hole 2 on the upper end of the column 8.
The upper end of the frame is fixed to the upper beam 14.

In addition, although the case of a pipe column has been described above, the case of a pipe column is not excluded, and the column can also have a similar structure.

(Effect of the invention) Since the present invention is constructed as described above, the spacer can prevent a gap from forming between the end face of the column and the end fitting, and the bolt attached to the end fitting can be prevented from forming by the spacer. This has the advantage of preventing the bolt head from sinking into the end face of the column and causing deviations in the column height and shaft assembly.
